This invention relates to a carbon eliminator, and more particularly,has reference to a device of this type adapted to eliminate the carbonin gasoline engines. V

The injurious efiect of carbon upon gasoline engines is of course Wellknown, and need not be dwelt upon at length herein. As is well known,engines free or substantially free of carbon operate with considerablyless friction, and as a result havemaximum power accompanied by a 'clearand distinct saving in fuel.

an engine below the carburetor; spaced partitions in said container andrespectively notched at opposite ends to cause air flowing through thecontainer to move through a tortuous path; and

' cylindrical screen containers mounted upon and extending between saidpartitions and projecting beyond opposite sides of said partitions,saidscreen containers each being filled with chemicals incrystal formadapted to attack carbon by causing a chemical reaction creating a gaswhich will soattack-the carbon.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claim, it being understood that changes maybemade in the construction and arrangementof parts without departing fromthe spirit of the invention as claimed. 7

Referring to the drawings: Fig. 1 is a perspective view, portions beingbroken away of a carbon eliminator formed in accordance with theinvention.

Fig. 2.is a side elevationalview showing the partitions and the chemicalcarryingcontainers supported thereby. j Fig. 3 is an end elevationalview of said partitions and chemical containers. e

Referring to the drawings in detail, 5 is a metal box here shown asrectangular in form, but which can in accordance with the invention takeother shapes. The box 5 is formed at one 1 Claim. (Cl. 123-498) asclearly shown from Fig. 1.

2. end with a plurality of air intake openings 6, through which airmoves into the box in the direction of the arrows illustrated in Fi 1.

The box is provided with a cover I which once attached to the box ispreferably secured thereto in a manner toseal the box tightly againstthe admission of air except through the air intake openings; The lid 1can be soldered or otherwise rigidly secured in a sealing relationshipto the box.

At the other end of the box, said box is provided with a fitting orcoupling 8 whereby there can be attached thereto a copper tube 9 or thelike, leading to the intake manifold, not shown, of a gasoline engine,immediately below the carbureter.

The fitting 8 represents an outlet opening for the box, disposed at theopposite end thereof from the air intake openings 6, and disposedadjacent the top of the box, as distinguished from the air intakeopenings 6, which are disposed near the bottom of the box.

Within the box, there are mounted spaced partitions l0 and II that aremounted in upright position within the box, one of these partitionsbeing disposed near one end of the box and the other partition beingdisposed near the other end, The partition l0 engages the box along allits edges, and the bottom edge of the partition I0 is formed with. anotched indentation I2. Thus, since all the edges of the partition l0tightly engage the side walls, bottom, and top of the box, air can movepast the partition l0 only through the aperture l2.

The partition II is of approximately the same shape as the partition l0,and is identical to said partition with the exception that the partitionI l is formed with a notch [3 at the topof the partition asdistinguished from the partition it] which has its notch at the bottom.

The partitions are formed with aligned openings M, in suitable number,and extending through these openings between the partitions, andprojecting beyond each of the partitions as best shown in Fig. 2, arethe cylindrical wire mesh containers l5 each of which is filled withchemicals [6 in crystal form, which chemicals will be described in moredetails hereinafter. These chemicals are of such a nature as to set up achemical reaction when air passes therethrough, which chemical reactionsets up a as which is drawn with the air into the combustion chambersand which, after beingexploded, operates to attack and eliminate carbonformation upon the engine parts.

As may be noted from Fig. 3, the cylindrical screen containers l5 can beclosed at the ends simply by folding over the flaps ll defined at saidends of the container, thus to close the screen containers completelyfor the purpose of retaining the chemicals 16 therein.

The screen containers l5 preferably extend practically from end wall toend wall of the box 5, so as to have. maximum effect upon air moving inthe tortuous path through thebox.

Considering the passage of said air, it may be noted that as a suctionis set up in the intake manifold, air will be drawn through the airintake openings 6, and will be caused to move upwardly in end chamber l8defined between the partition H and the adjacent end wall of the boxfi.'This air moving upwardly through-.t-he-end chamber 18, is caused tomove past and through the pro-- jecting end portions of the wiremeshcontainer l1, thus to cause the aforementioned chemical reaction tobe instituted.

Thereafter, I the air passes through the :note I3 at the top 'of thepartition H, into a middle chamber 19, and moves downwardly'through this'--1 i1iddle' chamber, through medial portions of the chmical containers[5, so as to be further acted upon by the chemicals in said containers.

Thereafterjthe air moves out of the middle to move through the outletopening 8 by the suc 'tion' action mentioned "above, and then through"the coppertubing '9 into the intake manifold.

After mixture withthe'engine fuel, and explosion,

said gases attack'the'car'bon that otherwise would tend to formupontheengine parts.

With respect to the chemicals which I have foundadvantageousfor thepurpose'of obtaining the desired results, I-pro'vide amixture ofchemicals .in' crystallized form as follows:

Parts 5 NHiCl--Am1nonium chloride 3 CaCl22H2Oj-Calcium' chloride l 3 CiHsOeTartaric acid 2 Zn'Cl2Zinc "chloride l. 1. "Sodium chloride; l 1

The gas which occurs through the chemical reactionprcviouslymentioned isnot injurious in any way to metal, although it efficiently attacks andin eifect eliminates the carbon tending to form upon engine parts. anddestroys the greater percentage'of the carbon monoxide gas which wouldotherwise be present.

This'gas further-attacks "Byreason of=a carbon-eliminator constructed inccordance with the invention, and mounted in-a vehicle adjacenttheengine and in the position stated, the engine will be allowed to runsubstantially free of carbon, thus to bemore flexible in operation andto operate with less friction, -with'a resultant increase in'po-wer ac-*companied by a saving infuel.

It is pertinent toconsider further exactly I how the chemicalsoperate toeliminate carbondeposits that otherwise would tend to 'form upon metalparts of the engine. In this connection, ammonium chloride,- zincchloride, tartar-icaoid,

4 and sodium chloride, with a small amount of moisture, will removecarbon from metal. Calcium chloride furnishes the necessary moisture toassist in the creation of gas, the generation of the gas further beingeiiected by the circulation of air around the foraminous tubes. The gasso generated is drawn into the intake manifold with said circulatingair, by suction set up in the intake manifold by operation of theengine. This .gasisfdrawnunto the intake'manifold below the carburetor,that'is, beyondthe outlet side of the carburetor. It feeds, along withthe fuel-air mixture that enters the intake manifold from thecarburetor, to the engine cylinders and during the explosion of thefuel-air mixture and after said e'xplosio'n, the chemical analysis ofthe generated .gasdoes not change.

In this regard, if it were tochange it would 'not have any effect uponthe carbon. As to the eilect of the gaseous compound upon the carbon, itshould be noted that it does notlchange thecarbon'to a gas, but onlyloosens the carbon deposits from the metal parts, whereupon the loosenedcarbon particles are blown out through the exhaust.

Whatis claimed is:
